of the regulator; and Fig. 5,a longitudinal sec-: tion through the rear part thereof, showingit closed;

The regulator consists, essentially, of a til, bular casing a, made of rubber and of a sizetosnugly fit the gas-service pipe b. A flange a on the rear edge of casing to projects into a pipe-coupling c and holds the casing against longitudinal displacement under gas-pressure. The transversely-extendingbase of the 1 casing a is fiat or disk-shaped and is di'-" vided by radial incisions into a number- 0f sector-shaped straight flaps d, each of which constitutes a valvethat checks the pressure from the outflowing gas. The transverselyextending head of the casing is bulged and is divided by similar radial incisions into the sector-shaped curved outwardlyopening valves 6. The casing is fitted into the gasservice pipe between the meter f and the gas burner or outlet 9 and in close proximity to the meter.

Under pressure' from themeter the valves (1 6 will partly! open, Fig.1, and permit the passage of 1a limitedquantityfof gas to'the burner. Under-back pressure the valve's'e' will close, Fig. 4, and prevent the gas from re entering the casing a, and consequently from reinfluen'cing the meter. As under backjpressure thereis no pressure on the valves (1, these valves siliency.

I Itwillbeseentha't improvedregulatoi prevents an' excessive gas;pressu-re in the willi also close by their own remain from being transmitted to the burner,

so that an even flow is providedand the cost A or. consumption is reduced. Foreign sub stances will be retained and prevented from? choking the burner. The regulator may be used for illuminating-burners, heating-burm "ers,and-gas-engines. I

What I claim is p 1. 'A gas-regulator composed of a flexible.

,tubular casing having a slitted transversely extendingfbase and a slitted transversely en tending head, to form two setspofoutwardly opening valves, substantially as specified.

"2. A gas-regulator composed of a flexible tubular casing having a flat radially-slitted base and a bulged radially-slitted head, to

form two sets ofoutwardly-opening valves,

substantially as specified.
